      Valgrind warning happpens because of uninitialized null bytes.
      In row_sel_push_cache_row_for_mysql() function we fill fetch cache
      with necessary field values, row_sel_store_mysql_rec() is called
      for this and leaves null bytes untouched.
      Later row_sel_pop_cached_row_for_mysql() rewrites table record
      buffer with uninited null bytes. We can see the problem from the
      test case:
      At 'SELECT...' we call row_sel_push...->row_sel_store...->row_sel_pop_cached...
      chain which rewrites table->record[0] buffer with uninitialized null bytes.
      When we call 'UPDATE...' statement, compare_record uses this buffer and
      valgrind warning occurs.
      The fix is to init null bytes with default values.

      storage/innobase/row/row0sel.c:
        init null bytes with default values as they might be
        left uninitialized in some cases and these uninited bytes
        might be copied into mysql record buffer that leads to
        valgrind warnings on next use of the buffer.
